Compatibility with guard v2.x

 - Extend Guard::Plugin instead of Guard::Guard
 - Fix RSpecs to avoid problem with uninitialised guard internals

Guard 2.8.x deprecated the use of Guard::Guard over a year ago.
Use of guard-kitchen generates deprecation warnings.

Guard 2.9.x removed guard/guard.rb breaking anything that extends
Guard::Guard (such as guard-kitchen
